From d6782712a14985d292f060d1fa1684b1dc2c02cd Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 10 Nov 2015 21:33:52 -0800 Subject: meta/generate_mipmap: Save and restore the sampler using gl_sampler_object instead of GL API object handle Some meta operations can be called recursively. Future changes (the "Don't pollute the ... namespace" changes) will cause objects with invalid names to be used. If a nested meta operation tries to restore an object named 0xDEADBEEF, it will fail.
